Just had a little e-mail exchange with Lisa at www.myoilshop.com They do sell the Redline 5W-40 also. Price is the same as all other street motor oils. It's not on their web site yet, but she said that they are going to update the site sometime in the near future. Redline 5W-40 looks like the ticket for a summer oil to me!!! Not much ehavier at 40C with a lot more upper end viscosity. Just thought you'd be interested.
